Applications:Â
UV-P is a benzotriazole type UV absorber. Characterized by its
strong, broad range UV absorption property, UV-P brings an
excellent photostability to polymers against UV light exposure in
many ways i.e. retarding color yellowing , preventing
embrittlement, maintaining of mechanical properties etc.
* Styrenic polymers: 0.**0.5wt% for PS based on polymer wt.
0.**0.5wt% for ABS based on polymer wt.
0.**2.0wt% for HIPS based on polymer wt.
* Polyvinyl chloride: 0.**0.5wt% for PVC based on polymer wt.
* Polyurethane: 0.**1.0wt% for PS based on polymer wt.
* Polyacrylate: 0.***0.3wt% for PS based on polymer wt.
* Polycarbonate: 0.***0.3wt% for PS based on polymer wt.
* Unsturated Polyester: 0.**0.4wt% for PS based on polymer wt.
ADVANTAGE
* Very high photostability for its strong ability to absorb light
especially in UV region(******0nm)
* Odorless, does not bring smells to the polymers.
* Very stable to heat, and can be used in plastics which require
high processing temperature.
* Low vapor pressure, very little or no loss during processing.
Stability and Storage:Â
In a closed system and dry, dark place without any light
exposure.
Package: *5 kg drum with inner PE bag
Shelf life: *4 months
